The Lice Life Cycle

To fully understand why a hair straightener isn’t the best solution, let’s take a closer look at the life cycle of lice.

  1. Nits (eggs): Lice eggs, called nits, are laid by adult female lice close to the scalp. They take about a week to hatch.
  2. Nymphs: Once hatched, baby lice are called nymphs. They grow into adult lice within 9 to 12 days.
  3. Adult lice: Adult lice can live up to 30 days on a human head. They feed on blood and lay more eggs, continuing the cycle.

Straightening the Facts: The Pros and Cons of Using a Hair Straightener


  • Heat kills: A hair straightener can kill adult lice and some nits when applied correctly at high temperatures.
  • Instant results: If a louse is trapped between the plates of a straightener, it’ll be killed instantly.


  • Missed nits: Straighteners can’t reach nits close to the scalp due to the risk of burning the skin.
  • Ineffective on wet hair: Lice treatments often require wet hair, but using a straightener on wet hair can cause damage.
  • Damage to hair: Frequent use of a hair straightener can cause long-term damage, such as split ends and breakage.
  • Not foolproof: A single missed louse or nit can lead to a re-infestation.

  4. Manual nitpicking: Meticulously combing through the hair with a fine-toothed comb can help remove lice and nits. This method requires patience and precision.
  5. Home remedies: While not always scientifically proven, some people swear by home remedies like tea tree oil, coconut oil, or vinegar to treat lice.
  6. Professional lice removal services: If all else fails, consider seeking help from a professional lice removal service.

Prevention is Better than Cure

Now that we’ve addressed the question, “Does hair straightener kill lice?” it’s crucial to focus on preventing future infestations. Here are some tips to keep lice at bay:

  • Seal non-washable items: Place non-washable items like stuffed animals in a sealed plastic bag for two weeks to kill any remaining lice and nits.

  • Keep pets clean and groomed: Regular grooming and cleaning of pet bedding can help prevent the spread of pet-specific lice and contribute to a lice-free environment in your home.

Natural Alternatives: Are They Worth a Shot?

Essential Oils and Home Remedies

  • Tea tree oil: Some people believe that tea tree oil can kill lice and nits, but research on its effectiveness is limited.
  • Neem oil: Neem oil is thought to have insecticidal properties, making it a potential natural lice treatment. However, more research is needed to confirm its effectiveness.

Herbal Lice Repellents: Do They Work?

  • Herbal sprays and shampoos: Some products on the market claim to use herbal ingredients to repel lice. While these products may have a pleasant scent and make the user feel proactive, their effectiveness in repelling lice is not well-established.
  • Ingredients to look for: Certain essential oils, like lavender, eucalyptus, and peppermint, have been suggested as potential lice repellents. However, more research is needed to confirm their efficacy in repelling lice.
